Brown Tumors Mimicking Skeletal Metastases: A Diagnostic Pitfall in Primary Hyperparathyroidism. [PDF]
Clin Case RepABSTRACT Brown tumors are rare but important manifestations of primary hyperparathyroidism (PHPT). These benign, fibrotic, and erosive bony lesions result from localized rapid osteoclastic activity driven by excessive parathyroid hormone levels. Although brown tumors are considered one of the most pathognomonic signs of PHPT, they are infrequently ...

Generalised osteitis fibrosa cystica due to secondary hyperparathyroidism in chronic kidney disease
Journal of College of Medical Sciences-Nepal, 2014 Secondary hyperparathyroidism is a frequent complication of patients with chronic kidney disease and is characterized by excessive serum parathyroid hormone levels and an imbalance in calcium and phosphorus metabolism.

Malignant mimic: Brown tumours of primary hyperparathyroidism
Journal of Clinical and Translational Endocrinology Case Reports, 2022 Hyperparathyroidism may lead to skeletal (osteitis fibrosa cystica) and renal complications; however, these are now uncommon in developed countries where hypercalcemia is detected earlier on biochemical screening and prior to the development of overt ...

Widespread presentation of brown tumors mimicking multiple myeloma
European Journal of Hybrid Imaging, 2023 Brown tumors or osteitis fibrosa cystica has become a rare presentation of primary hyperparathyroidism in up-to-date clinical practice. Here, we describe a case of longstanding untreated hyperparathyroidism presenting itself with brown tumors in a 65 ...

Occult Pulmonary Neuroendocrine Tumor Causing Severe Hyperparathyroidism: Diagnostic Challenges and Clinical Outcomes [PDF]
, 2022 Background/Objective: Ectopic tumoral production of parathyroid hormone (PTH) is rare. The incidence of hyperparathyroidism and osteitis fibrosa cystica (OFC) secondary to ectopic PTH secretion has only been reported in case reports, although infrequent.

Brown tumour in chronic kidney disease: revisiting an old disease with a new perspective [PDF]
, 2023 Osteitis fibrosa cystica (OFC) and Brown Tumours are two related but distinct types of bone lesions that result from the overactivity of osteoclasts and are most often associated with chronic kidney disease (CKD).
